What is the crust?
100
This is the movement of tectonic plates along a fault
What is an earthquake?
100
The type of mountain formed when large blocks of rock squeeze together due to stress of COMPRESSION.
What is a folded Mountain?
100
The type of rock formed from HEAT and Pressure.
What is a metamorphic rock?
100
Type of mountain formed by molten rock that erupts from beneath Earth's surface.
What is volcanic mountain?
200
The innermost compositional layer of Earth.
What is the core?
200
The point UNDERGROUND where an earthquake's FIRST movements occur.
What is the focus?
200
A fault-block mountain is formed by this type of stress
What can the stress TENSION form?
200
Two fault blocks moving past each other horizontally.
What is a strike-slip fault?
200
Type of volcano that has gently sloping sides and erupts nonexplosively.

300
Plates separate at this boundary.
What is divergent?
300
this is how an igneous rock is formed.

What is the asthenosphere?
400
The point on Earth's surface directly above the focus.

400
The type of stress found at a strike-slip fault.
What is shear stress?
400
This has to happen for a sedimentary rock to form.
What is cementation and compaction of sediment?
400
Type of eruption that is associated with the release of pyroclastic materials.
